When a group of people work together to reach the same goal, they make up a team. Team work is very important as men try to learn more about the world in which we live. In 1957, a team of eighteen men from the United States spent the winter at the South Pole. They were there to study the secrets of the earth and the sky. The South Pole is at the bottom of the world. During its winter, the sun never rises. The men had to face the darkness of a six-month night, as well as the world’s worst weather. The men lived in a group of buildings joined together by tunnels. They were cut off from the rest of the world. During the long winter, they could not be reached even by plane. The men depended on one another for company. They also shared certain tasks. Everyone took turns working in the "snow mine". This was a giant (巨大的) cave dug into the ice beneath their camp. There, they dug out clean snow needed as water supply. Each man also had his own important job to do. There was a cook and a doctor. There were scientists and men who were trained in other jobs. Working together, they proved that men can live and work at the South Pole.
